Testing 200 Mbps 4K 60P on the Yi 4K+
 

I set the bitrate at 200 Mbps and shot for 1.25 hours, resulting in 47 GB's of video clips. The temperature was 76 F, with direct sunlight. No overheating, no frames dropped. Perfectly normal, except for somewhat higher battery draw, but I had still had 33% left when I stopped.

Here is the 200 Mbps-shot 4K 60P video:


This "hack" does not alter the firmware, it just loads the settings in memory. Doing that does not invalidate the warranty, and is easy to install.

Does 200 Mbps make a difference compared with the default of 135 Mbps (a 50% increase)? Who knows; but it does not hurt!

Wow! - where did you get this hack from? It sounds interesting 😊.

Even without this hack, this is a little beast of a camera, which I mainly use for wideangle shots (recording 2.7k50p or 4k50p) with other cameras.

I've got a classical concert coming up this December at an Anglican-style church venue (to accomodate 500 people approx), where I'm going to use two of these little beasts (balcony shot, and audience shot from stage).

Thanks for your clips 😊

Gorgeous image! I would be afraid of the hack.....just my luck that I would brick my camera.

It would sure be nice if someone were to shoot a stage event with this great little camera to see if it would even be usable in such a senario.
The outdoor footage is very nice from this camera but even an analog sd camera looks good when shooting brightly lit outdoor scenes. The RX0 with its 1" sensor will mostlikely cut it indoors but will this super Yi4k+?

Here's a "stage event" night-time video:

Re: Report on the Yi 4K+
 

It's even better under stadium lights than daylight. Very impressive.
Were you in stealth mode because no one seemed aware yet the footage is so stable it looks like tripod.
The players were a tad hot, is there exposure compensation (must be). This is a very competent little 4k camera.
btw I shoot a local high school teams game video where a hundred spectators is a good crowd. lol what a great spectacle this college game must have been.
Now I have to decide between this cam and a fat tire bike lol again

Re: Report on the Yi 4K+
 

The stadium footage is nice and sharp and very stable as has been mentioned, but not really what I would describe as low light conditions but brightly lit night time. The large stadium lights are giving maximum lighting coverage for the game which is way above the sort of lighting available at an indoor evening function or amateur stage production where I would need good low light performance. I can achieve useable and quite sharp footage from a GoPro using a small video light to bring up the level just as the stadium lights are doing, but using lighting can be distracting and annoying at wedding receptions for example.

What would be a great comparison, would be footage shot in a bar at night, or at a party, disco or theatre show to really show low light performance if you get the chance at all.

Damn! It would be interesting to mount a Yi 4K+ at the top of a goal post on each end of the field. Field of view would be from the goal line out to thirty yards. I really would like to edit that with footage from a 4K camera that is following the play.

I know a High School coach that would go for it. Can I borrow a couple of Yi 4K+ cameras (LOL)? What is the largest card the camera can use? Can an external battery be used?

Re: Report on the Yi 4K+
 

256GB card; yes, an external battery can be used to power the camera, even without an internal battery. The card would give 4 hours of 4K 60P video at 135Mbps.

Re: Report on the Yi 4K+
 

I'm noticing a fair amount of micro shakes in some shots, did you post any videos where you had the EIS turned on?

cheers

Re: Report on the Yi 4K+
 

Yeah me too
Camera angles all have to be more or less on the same side of the field of play otherwise everybody is coming and going willy nilly and its disorienting for a viewer so you couldn't have shots from both ends in the same play
